JAMES W. PARKER, OF WEST PULLMAN, ILLINOIS.

SHEAF-C ARRIER.

SPECIFICATION forming part of Letters Patent N 0. 738,838, dated.September 15, 1903.

Application filed January 15, 1902. Serial No- 89.899. (No model.)

To a'IZZ whom it may concern.-

Be it known that 1, JAMES WV. PARKER, a citizen of the United States,residing at West Pullman, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in sheaf-Carriers, ofwhich the following is a specification.

This invention relates to certain new and useful improvements insheaf-carriers for grain-binders, corn-harvesters, and the like; and ithas for its objects, among others, to provide a simple and cheap yetpositive and efficient construction by which the bundles will beautomatically dumped at predetermined periods.

I provide a trip-arm designed to engage the previously-do mped sheavesand thus tripping the carrier. The tripping-arm is connected by novelmeans with the crank-arm, so that when the tripping-arm is acting oractuated by its engagement with the dumped sheaves it will cause thelifting of a pulley, and this lifting of the pulley by the meanshereinafter described will throw the crank off its center and so allowthe fingers of the carrier to drop and release the sheaves. The pitmanis provided with a roller under which the chain connected to the framepasses, and a second roller or pulley is provided over which the saidchain passes, this second roller being so disposed as to bring the samein line with the point of connection of the chain with the tripping-armand thus avoid friction.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the numerals of reference marked thereon, form a part ofthis specification, and in which- Figure 1 is a plan view showing theapplication of my present invention. Fig. 2 is a detail view with theparts in the position they assume when the fingers of the sheaf-carrierare elevated. Fig. 3 is a similar view with the fingers of thesheaf-carrier dropped. Fig. at is a rear sectional elevation.

Like numerals of reference indicate like parts in the different views.

Referring nowto the details of the drawings, 1 designates the fingers ofa sheaf carrier,

and 2 the shaft to which they are attached. 3 is the pivot of the saidshaft and 4 the tripping-arm, which is pivoted or hinged at its innerend, as seen at 5, and the shaft 2, near the vertical pivot 3, ispivoted at 25 in the frame to allow the shaft 2 to turn in the frame.

6 is a short piece of chain attached at one end to a lug or eye oranalogous device 7, affixed to the inner end of the trip-arm, and itsother end is connected to one end of a rod or bar 9, the other end ofwhich is attached, as

at 10, to one end of a chain 11, which passes 18 is a roller or pulleycarried by the pit man near the center of its length, and under thispulley passes the chain 11, the other end of which is connected to thearm 19, connected with the post of the binder, as shown.

W'ith the parts constructed and arranged substantially as abovedescribed the operation is as follows: When the arm 4: meets a dumpedsheaf, it is made to move on. its pivot. In its swing backward it pullsthe rod 9 and chain 11, and this carries the pulley 18 into the positionindicated by Fig. 3. The lifting of this pulley throws the crank 15 offits center, and thus allows the fingers of the carrier to drop andrelease the sheaves. By placing the roller 12 at the point described andshown I not only bring the end of the chain 11 in line with the roller18 and the hinge of the trip-arm, but provide for the folding of thecarrier without unhooking the chain. Each time the tripping-arm is swungon its pivot by reason of its engagement with a previouslydumped sheafthe pulley 18 will be lifted and the crank thrown off its center, so asto permit of the dropping of the fingers of the carrier and theconsequent dumping of the bundles or sheaves.

It will thus be seen that I have provided a novel and cheap constructionby which the This pulley or roller is Too sheaves willbe automaticallydumped, and the parts being compactly arranged and in such position asnot to be liable to injury during the operation of the machine there isno danger of the parts becoming deranged, and while the structuralembodiment of the invention as herein disclosed is what 1 at the presenttime consider the preferable one it is evident that changes,variations,- and modifications may be resorted to without departing fromthe spirit of the invention or sacrificing any of its advantages, and Itherefore reserve the right to make such changes, variations, andmodifications as come properly within the scope of the protectionprayed.

What I claim as new is 1. The combination of a pivoted trippingarm, acrank, the shaft of the carrier, a connection between said shaft andcrank, a connection between the tripping-arm and frame of the binder,and the pulley on the connection between the crank and shaft and engagedby the connection between the tripping-arm and binder-frame to be raisedas the trippingarm swings backward.

2. In a sheaf-carrier, the combination of a frame, a shaft pivoted insaid frame at its inner end, a tripping-arm pivoted to the outer end ofsaid shaft, a carrier mounted upon the shaft, a crank mounted in theframe, a pitman having one end connected to the crank and the other endconnected to the shaft, connections between the shaft, pitman andtripping-arm, and guides for said connections.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES W. PARKER.
